AUTOMATIC PAPER-CONTAINER-MAKING MACHINE.

Application filed. August 9, 1922. Serial No. 580,695.-

To all whom it may concern:

Be it known that I, ARON BRAUJsTEIN, a citizen of the United States, residing in San Antonio, in the county of Bexar and State of Texas, have invented a certain new and useful Improvement of an Automatic Paper- Container-Making Machine; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1 it appertains to make and use the same.

This invention relates to improvements in machines for making paper containers, and more particularly to mechanism for forming a substantially bottle-shaped paper contalner from a substantially conical-shaped blank.

The primary object of the invention is to furnish a. machine adapted to corrugate the upper and lower pOItiOns of a substantially conical-shaped paper blank and to subsequently fold the corrugations at the lower portion of the blank to provide a. cylindrical portion, and to also fold the corrugations at the upper portion of the blank and seal these last mentioned folded corrugations.

7 Another object of the invention is to provide instrumentalities for forming a paper receptacle of novel construction. I lVith the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

Referring to the drawings: a

Figure 1 is a perspective viewjpartly in section of the complete machine.

Fig. 2 is a similar view of a shaping shell or cover forming part of the machine.

Fig. 3 is a vertical sectional view of said shaping shell.

Fig. A is a perspective view of a core forming part of the improved blank shaping mechanism.

Fig. 5 is a vertical sectional view of said core.

In the drawings, 5 designates a revolving drum or turn table mounted on the frame of the machine and carrying a plurality of shaping and supporting cores 5*, four of which are illustrated for the purpose of disclosure. From the detail'views of the cores shown in Figures 4 and 5, it will be seen that each core consists of abase 1 from which extends an upwardly projecting hol low cylinder 1 provided with radial slots 1 Extending upwardly'from the upper edge of the cylinder, is a'hollow frusto cone 2 having a cap or head 2 provided with radially arranged slots 2". Arranged within the cylinder 1? is a frusto cone 4 from which rises a post 4: provided at its upper end with a disk 4:" from which projects upwardly extending substantially triangular shapedteeth 6 which move up and down in the slots 2*. The cylinder 1 is provided with arms 7 pivotally connected to the cylinder. These arms move inwardly and outwardly in the slots 1 and they are so weighted that their outer edges normallylie flush with the outer surface of the cylinder. When however, the frusto cone 4 is moved upwardly, its conical which have theirupper ends surface willengagethe inner lower edges of the arms 7 and project said arms radially as shown by the dotted lines 3. During this movement the post 4 functions to force the teeth 6 upwardly through the slots 2".

In manufacturing the improved containers, the blanks of conical shape are placed in inverted position on the cores, and while portion 1 of the core. The upper end of the cylinder 1 is provided with an inwardly extending annular flange l on which rests a ring 1 provided with a yoke 6. The cylinder 1 is provided with radial slots 2, which when the shell is placed over the core, are adapted to receive the paper of the lower portion of the blank and the arms 7. j In other words, when the arms 7 are moved outwardly, they force portions of the paper outwardly into the slots 2.

The ring 1 is provided with a plurality of pivoted flaps 3", which are radially ar ranged around the ring 1 and are spaced apart. These flaps 3 are connected bv links 4 to a disk 5, and this disk is supported by a shaft 5 that is capable of sliding vertically in the yoke 6. I

As shown in Fig. 1, the upper end of the shaft 5 is pivotally connected to a rocking lever 5, and this lever is actuated by a link 5". Any suitable means may be provided for reciprocating this link. The yoke 6 is rigidly connected to a sleeve 6 that surrounds the shaft 5 and the upper portion of this sleeve is provided with a pulley 6. The pulley is fixed to the sleeve and is driven by a belt '7. In. order to permit paper blanks to be simultaneously operated upon both the'core andshell, each core, as shown -i'n'l3ig. 5, is preferably provided with adepending spindle (not shown), and when the core is in a position under I the shell 1, the spindle may be raised by outwardly and the teeth 6 will any suitable means (not shown) so that the core will enter said shell. As the core moves intothe shell, the lower edge ofthe shell will strike a lever 5 forming part of the core, and this lever'will elevate the cone 1, so thatthe arms 7 will be projected be raised. As the arms 7 move outwardly they force the paper forming the lower portion of the cone shaped blank into the slots 2 of the shell and thus form corrugations. Then the link 5 is operated to depressthe flaps 3 and these flaps will move downwardly between the teeth 6 and thus form corrugations at the apex of the blank. Then the core may be lowered suiiiciently to release the lever 5 and thus permit the teeth 6 and arms ,7 to withdraw into the body of the cone. Then the belt 7 may be set in motion to rotate the shell 1 and this will cause the inner surface 1 of the shell to fold the corrugations at the lower portion of the blank and at the same time the flaps 3 of the shell will smooth down or told the corrugations at the pinnacle of the blank.

When the blank has thus been shaped the core may be lowered and then the turn table 5 may be shifted to bring the blank into a position beneath the final shaper 3. At this position, the core maybe raised to bring the folded blank within the final shaper 3 and as this final shaper has interior formation similar to the shape of the blank, the blank w ll snugly fit within This member "then suitable means in order to the blank the member 3 rotated byany press the folded corrugations of into a permanent position.

' After the final shaping of the blank, the core is again lowered and the turn table is shifted to bring the shaped blank and the core-on which it is mounted, to a position below the sealing member 4 This member is adapted to carry a gummed tape and means for severing this tape into small disks, which are pressed onto the folded upper end of the blank. The sealing member 4 is supported by'a rod 4, which is connected to one end of a rocking lever 4 that is actuated by a link 4 It is obvious that the link 5 may be oper- 7 outwardly.
